Avoid these common mistakes to protect your wood effectively
Impregnating wood is not complicated, but an inexperienced person can easily make mistakes that significantly reduce its effectiveness. Knowing what to pay attention to and what to avoid during impregnation is worth learning to avoid common pitfalls.
Impregnation is crucial if you want to take care of furniture or other wooden elements—especially outdoors and exposed to the elements. This could include a deck or garden furniture. What mistakes should you avoid during impregnation?
Impregnating wood: Common mistakes
One of the most common mistakes is improperly preparing the wood surface before applying the impregnating agent. The wood should be clean and dry before beginning the impregnation process. However, people often fail to thoroughly clean the wood of dust, dirt, grease, moss, or mould, which results in uneven absorption of the impregnating agent.
Also, old paint, varnish, or previous impregnation layers should be removed. Applying a new impregnating agent on an unclean surface prevents the agent from penetrating deeply into the wood, weakening its effectiveness. It's also important to sand the wood with sandpaper to ensure a smooth surface that better absorbs the impregnant.
Weather conditions are another significant factor that is often ignored. Wood should be impregnated in suitable weather—dry days with stable atmospheric conditions are key. Some make the mistake of impregnating wood in high humidity, not to mention rain. Moist wood does not properly absorb the paint, reducing its effectiveness.
Extreme temperatures can also negatively affect the impregnation process. Too low temperatures cause the impregnant to penetrate too slowly, while high temperatures accelerate its drying, leading to uneven absorption. Direct sunlight during application is also not recommended, as the rapid drying of the substance can result in stains and poor wood protection.
Another common mistake is choosing the wrong impregnant. Various protective agents are available on the market, and choosing the right product is crucial. Unfortunately, many people opt for the wrong impregnant, not suited for the specific type of wood. Exotic wood, for example, requires specialised impregnating agents that offer better protection.
Lack of UV protection is also a frequent mistake. A UV-filtering agent should protect Wood from direct sunlight to prevent fading and material degradation. It’s also important to pay attention to the composition of the impregnant to avoid products containing substances harmful to the wood or the environment.
How to properly apply wood impregnant?
Mistakes are easy to make during the impregnant application stage as well. Uneven application of the protective agent is a common problem that leads to stains and uneven protection.
The impregnant should be applied along the wood grain to ensure even absorption. Another common mistake is using a layer of impregnant that is too thick. Instead, applying several thin layers is better, allowing for better absorption and ensuring lasting protection. It’s also important to let each layer of impregnant dry completely before applying the next one. Neglecting this step can result in poor adhesion and weak protection.
Remember to regularly impregnate wood
Impregnation is a process that needs periodic renewal to maintain its protective properties. Unfortunately, many people forget this, leading to faster wood degradation. Wood outdoors is constantly exposed to the elements, so a new layer of impregnant should be applied every few years (depending on conditions and usage intensity).
Regular inspection and repair of minor damages are also crucial for long-term protection. Small scratches and damages can become entry points for moisture and contaminants, so it’s worth repairing them quickly.
